This invention relates to toilets, and particularly to toilets of thecharacter used in summer cottages, farmsgcabins', camp trailers, boats,or in fact any place where the conventional type of plumbing has notbeen installed. Many types of so-called chemical toilets have been onthe market'for a number of years using a container into which isplaced aquantity of water, and the water is intermixed with some chemical whichis supposed to dissolve the refuse, or a deodorant is placed thereinwhich is supposed to overcome the odors emanating from the refuse.Toilets of this type, in addition to being unsanitary, are not odorless,especially during the summer season when a cottage or camp trailer issubject to high temperatures. In addition to the above, some of thechemicals and deodorants sold are very nauseating to many people. It isthe primary purpose of the invention herein described to provide a newand improved sanitary toilet which is selfcontained, and at the sametime providing a toilet approaching the advantages of the modern toiletinstalled in a location providing running water and modern sewagedisposal.

Another object of the present invention is to provide a new and improvedtoilet comprising a container into which is nested a new and. im-

proved bowl and valve assembly so constructed that odors cannot escapefrom the container below the bowl and valve assembly into thesurrounding atmosphere.

More specifically the object is to provide a bowl assembly having a bowlof such shape that it converges toward an opening which has an edge atthe lowermost point in said bowl, said opening being inclinedupwardly ina direction substantially parallel with one side of said bowl. Such abowl enables the use of a valve closure which, while effective foremptying the bowl, is not subject to collection of sediment such aswould be the case with a valve at the bottom of the bowl. It is alsopossible with such construction to cover the opening-and valve withwater thereby effectively sealing the same against escape of odors.

A still further object of the present invention is to provide a new andimproved valve and valve operating mechanism for discharging refuse froma bowl assembly into a refuse container below the same.

Another object of the invention is to provide a new and improvedflushing means whereby a deposit of fresh water may be allowed to enterthe bowl portion of the toilet when desired by the operator. g

A further object is to provide new and improved means for locking thebowl assembly to the container.

A. still further object is to provide a new and improved toilet that isat all times odorless. and which does not require the use of chemicalsor deodorants at any time. i

The above and other objects of the invention will appear more fully fromthe following more detailed description; and from the drawing Where-Fig. l is a top plan view of my invention; Fig. 2 is a section takensubstantially on the line 2-2 of Fig. 1; and

Fig. 3 is a portion of a section taken substantially on the line 3-3 ofFig. 1, and showing the top bowl portion clamped to the containerportion in accordance with the principles of my invention.

Referring now to the drawing, the numeral l0 designates a container orother sewage receiver of any suitable size or shape, but as shown bestin Fig. 2 of the drawing, is cylindrical in shape. The top of thecontainer [0 is bent to form a circumferential flange or ledge ll,'thestock being rolled to formv a bead l2, for a purpose later to bedescribed. The bowl I3 is formed in one piece, as shown best in Fig.2,to define a sump orcontainer, the upper portion thereof being bent toform a wide circumferential flange l4, thestock being bent'around .toform a narrow circumferentia1 flange l5 adapted to be aligned with andrest upon flange ll of container ISL. Interposed between flanges II andI5 is disposed a gasket 5 to form a seal between thetcontainer. Ill andbowl l3 so that neither liquids nor gases may escape from the containerII].

There is provided an annular discharge orifice or opening ll in the bowll3, and to open and close this opening when desired there is provided avalve comprising an arc-shaped rubber member l8 secured to a metal discl9 by means of a bolt and nut 20. The metal disc it ishinged upon thepin 21 which passes through a pair of lugs 22 formed on the side of thebowl [3. A spring 23 to hold the valve [8 normally in a closed position,as shown best in Fig. 2, is bent around the pin 2| between the lugs 22,the'lower portion of the spring contacting the back of metal disc l9upon which valve I8 is secured.

It is to be noted that the opening H has its lower edge at the lowermostpoint in the bowl and that the opening is inclined and extends upwardlyin a direction substantially parallel with the side of the bowl.

To manually .actuate'valve l8 there is provided said projection into thecontainer I9.

a lever 24 secured to the handle 25 by means of the pin 26. The lever 24is journaled in sleeve 26, said sleeve being secured to the outside ofthe bowl of the toilet in any conventional manner, such as by solderingor riveting, and passes from the exterior to the interior of the toilet,as shown in Figs. 1 and 2. Lever 24 is bowed, within the container, toconform to the shape of bowl l3, and terminates in a cam portion 28.This cam 24 is adapted to engage pulley 29 which is secured to pin 30,the pin passing through lug 3| formed on metal disc I9. When lever 25 ismoved to the left, as shown in Fig. 2, lever 24, together with cam 28,is moved to the dotted line position of Fig. 2, cam 28 rolling throughpulley 29 and, as pulley 29 is secured to the back of metaldisc l9,valve I8 is raised from its seat allowing the contents of bowl l3 to bedeposited into container I].

So that the user will know definitely the height of the liquid incontainer I0, there is provided a projection 32 having an opening 35from A float 33 is disposed within this tube-like projection and thereis secured to the float 33 a measuring rod 34 which passes through anopening in the projection cap so that it may move vertically up or downaccording to the depth of the liquid in the projection 32. Thismeasuring rod is properly marked to show quarter full, half-full andfull so that the user will know exactly when the container I0 should beemptied.

A conventional toilet seat 31 having a cover 38 hinged thereto by meansof hinge 39, is secured and rests upon flange I4 by means of bolt andnut 40. The seat 31 protrudes slightly inward, as shown in Fig. 2, toform an overhang beyond the flange l4, so that all refuse will falldirectly into the water in bowl I3 and not strike the sides of bowl l3.

To refill the bowl l3 with water after valve l8 has been actuated, thereis provided a supply tank 4|, the same to be secured to the wall abovethe toilet at any convenient height to provide a gravity feed therefor.This tank is supplied with a tight fitting top to prevent loss of waterwhen the toilet is installed in a camp trailer, or other moving vehicle.A conventional release valve 42 is installed directly below the tank,the same being actuated by means of the lever 43 which has chain 44secured thereto, said chain being of suflicient length to facilitate theuser grasping handle 45 when it is desired to operate valve 42. Aflushing pipe 46, having a plurality of staggered apertures 41 therein,is disposed within the upper portion of bowl I3 and is held in place bymeans of coupling nut 52. Pipe 46 lies directly below and under theoverhang of seat 31, the same passing entirely around the innercircumference of bowl I3 and passes out through the side wall of thebowl assembly where it is held in place by means of coupling nut 48. Theend of pipe 46 is open, a cork 49 being inserted therein as a plug whichmay be removed when it is desired to clean the pipe of foreign matterwhich has collected therein during use. Flexible tubing 59 is used toconnect tank 4| with pipe 46, said tubing being secured to the outletpipe of valve 42 and inlet end of pipe 46 by means of strap 5|. Strap 5|enables the user to disconnect flexible tubing 50 from pipe 48 when itis necessary to free the container ID from the water supply tank 4|.

Clamping means 53 are provided to secure the bowl |3 to the containerl0, said means comprising, as shown best in Fig. 3, a clip 54 secured tothe bowl by means of a rivet 55. The clip 54 is hinged on pin 56 andhooked member 51 is hinged within the member 54. As shown best in Fig.3, the hooked member 51 is shown engaged upon the bead 2 to secure thebowl and container sections of the device in locked engagement. Torelease securing means 53 the clip 54 is moved to the right to thedotted line position of Fig. 3, this allowing the hooked member 51,which is pivoted on pin 58, to free itself from bead H.

A bail 59 is secured to the container H] by any suitable means such asthe ears 6!] which are aligned on opposite sides of the container, asshown best in Fig. 1. The bail 59 enables the user to conveniently carrythe device when it is necessary to empty the container.

There is provided an opening in the lower portion of the container ID towhich is secured a threaded projection 6|. A threaded cap 62 is adaptedto engage the threaded projection 6| and close the opening into thecontainer.

The manner in which the device operates is as follows:

The water supply tank 4| is first filled to capacity and the coverplaced thereupon. To transfer a quantity of water from the supply tank4| to the bowl I 3, the user acuates valve 42 by pulling upon handle 45which in turn operates lever 43. The water flows by gravity down conduit50 into flushing pipe 46 where it is released through the plurality ofstaggered apertures 41 into bowl I3. When the desired quantity of waterhas been released, the handle 45 is released and valve 42 then closesautomatically. As valve I8 is in a closed position, as shown in Fig. 2,the water remains in the bowl I 3 and the toilet is ready for use. Whenit is desired to dump the contents of bowl l3, the user operates lever24, by means of handle 25, moving the same from right to left asillustrated in Fig. 2. Lever 24 being journaled in sleeve 21 andterminating in a cam 28, which in turn passes through pulley 29 which issecured to the back of valve l8, valve I8 is swung to an open positionagainst spring 23 to the dotted line position shown in Fig. 2. The waterin bowl l3 then passes out through opening H and dumps into containerI0. When handle 25 is released by the user, valve I8 is returned to itsnormal position, as shown in Fig. 2, by means of spring 23. Inasmuch asvalve I8 is of rubber and the circumference of opening I! is rounded,the arc-shaped rubber face of the valve forms a liquid tight seal. Whenvalve l8 has again been closed, the operator then releases valve 42 bymeans of chain pull 45 and another quantity of water is deposited inbowl l3. It will be noted from Fig. 2 that bowl |3 is so shaped that allrefuse will drop directly into the water in the bowl and will not strikethe unprotected sides of the bowl. Inasmuch as the water enters the bowlI 3 through apertured pipe 46, and as the holes in pipe 46 are staggeredthe water is directed toward the interior of the bowl in a plurality ofdirections thus effectively clearing the bowl with a minimum amount ofwater, a result of utmost importance in a unit to be used where only alimited quantity of water is available. When it is desired to cleanflushing pipe 45 of any sediment that might lodge therein, and thereforeplug apertures 41, the user simply removes the cork plug 49, Fig. 1,which closes the open end of flushing pipe 46, and any foreign matterlodged in the pipe will be carried away through this opening.

garners E T When the gauge: sticknfl. discloses that. the container-l0shouldv be emptiedpthe userxiisengagesiconduit 50 from. flushing-pipe-46, by loosening strap .5 l Bail 59 .may then be swung to ;a positionabove the device so that the con.- tainer may betransported. If twopeople wish to carry the container, the: same could be pro!- vided witha'handlepn .each side thereof similar to thehandlesjcommonlyseenonla'rge ash containers. During the period whenth'e device is beingtransportedatoithe locality where the refuse is to be buried, the valve18 remains closed and no odors may escape from the container Ill. Toempty the container, the clamping means 53 are opened by moving the clip54 to the right, as shown in Fig. 3, so that the hooked member 51 isfreed from the bead I2 of the container Ill. The entire bowl assembly isthen removed from the lower container I0 and the contents dumped. If theuser does not wish to carry the entire device to the dumping locality,the bowl assembly may be removed and a top cover which fits neatly overthe bead l2 of container l0, may be installed to prevent spilling andsplashing of the contents of the container during the carrying period.Container l0 may also be emptied by removing cap 62 from projection 6]and tilting the container sufiiciently to allow the contents to flow outthe opening in the container.

Should it be desired to install my device in a location where there isalready in use a toilet using a tank or other means of sewage disposal,the container l0 may be constructed as an openended cylinder which maybe fastened to the floor directly over the opening leading to the tankbelow. This would do away with the necessity of dumping the containerand also do away with the disagreeable odors so prevalent with toiletsof the tank type, the valve l8 being a complete seal against any escapeof gases from below ground.

I have described a new and. improved toilet that will be cheap tomanufacture and assemble, and yet it will provide the user with the samehigh efficiency of operation that one expects from the new and improvedtoilets installed in the newer buildings throughout the country. Itpro-- vides an ideal odorless toilet for camp trailers where the problemof refuse disposal has been one of real concern, inasmuch as a traileris on the road during the heat of summer and if a chemical is used,there is always some odor, even if it is that of the so-called deodorantitself. The water supply tank is fully enclosed so that there is nochance of spilling the contents while enroute.

While I have shown and described a satisfactory constructional exampleembodying the principles of the present invention, it will be understoodthat many changes, variations and modifications may be resorted towithout departing from such principles.
